Beautiful church from the early 19th century. The interior is currently undergoing major renovation, which is a shame about the view of the magnificent stained glass windows. Jointed stone walls, a few statuettes of Saints.

Grand-Champ is the seat of several centuries of history since the Neolithic. This small Breton village saw local lords build a number of chapels and manor houses during the 16th and 17th centuries. The Saint-Tugdal church in its center impresses with its neo-Gothic style.
